  • the document DE 10 2008 052 662 A1 discloses a mounting system for mounting photovoltaic elements, in particular on a house roof with low inclination or flat roof, wherein the mounting system rail elements and module support elements comprises, to which the photovoltaic element is fastened by means of fastening elements.
  • a mounting system comprising: a base rail having a longitudinal groove in its longitudinal direction, preferably one-sided, open receiving groove defined by side walls; a retaining rail having a base leg, a support leg and a Einsteckschenkel, wherein the retaining rail is tool-free with its base leg form-fitting inserted into the receiving groove of the base rail, so that the support leg protrudes from the receiving groove; and at least one clip which can be plugged onto the base rail from the outside in such a form-fitting manner that the side walls can no longer be bent outward in order to permanently fix the inserted holding rail in the base rail.
  • tool-less is understood below to mean assembling the system of the invention without the use of tools. The fitter works with his bare hands. A “permanent fixation” is to be understood below an assembly that can not solve itself.
  • the mounting system of the invention can be easily assembled without the use of tools.
  • the retaining rail is inserted into the base rail and fixed by means of clip-on brackets in the base rail.
  • the brackets prevent walls of the receiving groove can be bent to the outside (elastic) to release the inserted retaining rail.
  • the base rail, the retaining rail and the brackets are positively connected with each other and secured against each other.
  • a fitter can manually mount the retaining rail, e.g. with his foot from above on the holding rail occurs.
  • the retaining rail then bends the base rail, the retaining rail engages positively and the base rail moves back to its original position.
  • the brackets or the clip can be attached to the base rail in the same way. Both the assembly and disassembly can be done with hands and feet.
  • the brackets can also be removed with bare hands.
  • the system is characterized in particular by its modularity.
  • the rails can be designed to be of different lengths in order to set up PV modules of different sizes.
  • different number of support rails can be inserted one behind the other in the same base rail.
  • east-west orientation the same applies, in which case always two support rails are placed back to back in the or the base rails.
  • the support rails can be kept in a modular manner with different angles of attack and assembled as needed for a customer before the system is delivered to a construction site.
  • the mounting system can be used to set up PV modules in a "simple" configuration for a south orientation. If the system is provided "double", so that two support rails are positioned with their supporting legs back to back like a saddle roof, the PV modules can be set up in an east-west orientation.
  • the mounting system is universally applicable.
  • the PV modules can either be mounted directly on the support rails or inserted into a frame-like further system, which usually has holding and mounting rails. In this way framed and frameless PV modules can be mounted.
  • the support leg and the Einsteckschenkel are oriented substantially parallel to each other and each connected to the base leg.
  • the support leg and the Einsteckschenkel each include such an angle with the base leg, that the support leg and the Einsteckschenkel are preferably each oriented vertically. This is the best way to introduce the forces acting on the mounting system into the roof.
  • the retaining rail additionally has a support leg, which is connected to at least the support leg or the Einsteckschenkel to define a substantially triangular, in particular rectangular triangular, base (in a side view).
  • These "triangles" can be mounted on the bottom rail with a south orientation and an east-west orientation with a minimum distance to each other to achieve a maximum density of the roof with PV modules.
  • the support legs allow attachment of the, preferably framed, PV modules directly to the support rail. But the support legs also allow an arrangement of another system for mounting frameless PV modules. In this case, additional support rails, preferably in a vertical orientation, mounted on the support legs.
  • the support leg and the Einsteckschenkel are aligned vertically in an erected state of the mounting system, as already explained above.
  • the legs of the retaining rails are integrally formed.
  • the retaining rail then represents a single element, which is plugged into the base rail at the construction site.

  • the support rail can be pre-assembled in the base rail, so that a transport to the construction site and on the roof is easier.
  • the support leg and the Einsteckschenkel each have at least one positive locking lug, wherein the base rail correspondingly has at least one positive locking lug.
  • Relative layers and contours of the positive locking lugs are matched to effect a positive connection, so that the retaining rail is captive in the base rail can be inserted.
  • connection between the support rail and the base rail is positively, preferably exclusively by a positive connection and not by a frictional connection.
  • the fitter can insert the retaining rail into the base rail. Should it be necessary, he can step on the retaining rail, in order to put this into the receiving groove of the base rail. Tool is not needed.
  • the manufacture of the affected components of the mounting system is simplified, because e.g. only a single contour for all positive locking lugs are. The same applies to the position of the positive locking noses.
  • each clip correspondingly has at least one positive locking lug which corresponds with the form-fitting lugs of the base rails and the retaining rails with respect to position and contour, as stated above.

  • the receiving groove has a first side wall and a second side wall, wherein at least one of the side walls is formed flexible, wherein the first and second side walls are oriented substantially parallel to each other and wherein the first and second side walls are elasticallyjackbiegbar To create space for inserting the retaining rail preferably in the vertical direction in the receiving groove.
  • the side walls can be bent apart elastically. The bending apart can be done manually. In this way, space is created, which is required for insertion of the retaining rail in the receiving groove. As soon as the retaining rail is inserted, the side walls hold the retaining rail in the receiving groove. Also for this process no tool is needed.
  • each of the brackets has a cover, a first wing section and a second wing section, wherein the wing sections are connected to one another via the cover and wherein at least one of the wing sections is flexible.
  • the clamps are used to secure the side walls of the base rail against bending. If the base rail is secured against bending, inserted retaining rails can no longer be removed from the base rails. Since the base rail with inserted support rails are already relatively stable to use, it may be necessary for the clips to be flexible, i. in particular elastically bendable, are formed.
  • the clamps are also attached without tools on the base rail. The bending of the brackets is done by hand.
  • the clips, when attached to the base rail may be slid in the longitudinal direction to adjust a relative position of the clips to the sockets.
  • each clip is adapted to stiffen the side walls of the receiving groove against bending outward.

  • the base 24 may be slightly less high in the Z direction than the receiving groove 32 is deep. It is understood that the height of the base 24 but also can be as large as the depth of the receiving groove 32.
  • a slightly lower height of the base 24 ensures sufficient play in the height direction Z for adjusting or positioning the positive locking lugs 60 of the base 24 relative to the positive locking lugs 40 of the side walls 34 and 36.
  • Contours 92 of the positive locking lugs 40 and 68 of the base rail 16 and the bracket 26 are preferably exactly identical, whereas a contour 94 of the positive locking lug 60 of the base 24 may also differ slightly from the exact identity (congruence) by between a rising and falling edge of the positive locking lug 60, a straight portion in the height direction Z is provided to provide sufficient clearance in the height direction Z during insertion (see arrow 90).

  • the PV modules 12 make the system 10 torsionally rigid despite its lightweight construction.
  • the pedestals 24 can be secured in the base rails 16 by means of the brackets 26.

  • the attachment of the clamps 26 on the base rails 16 is again in the vertical direction (see arrow 90 in FIG Fig. 6A ).
  • the brackets 26 are so flexible, that is elastically flexible, designed such that the wing portions 70 (see. Fig. 4B ) can be easily slipped over the side walls 34 and 36 of the base rail 16.

  • the clip 26 can be loosely placed on the base rail 16 and then pressed under a higher pressure force down, for example, the fitter is on the bracket 26.
  • the brackets 26 prevent the side walls 34 and 36 of the base rail 16 from being bent outwardly. In this way, the pedestals 24 are secured in the base rails 16. In this way, the support rails 18 are secured against the base rails 16, even if the support rails 18 are not frictionally, but only positively connected to the sockets 24, as already explained above.
  • the upper bracket 26 has a distance A3 to the base 24 in the longitudinal direction X.
  • the lower bracket 26 has a distance A4 relative to the base 24 in the longitudinal direction X.
  • the distances A3 and A4 can be the same size.
  • the distances A3 and A4 can be different.

  • the lengths L2 and L3 can be approximately equal.
  • the length L2 of the pedestals 24 is slightly larger (eg 4 cm) than the length L3 (eg 2 to 3 cm) of the clamps 26.
  • the spacings A3 and A4 are usually of the order of 1 to 2 cm.
  • the inserted base 24 can be secured only by a bracket 26 in the base rails 16.
  • the length L3 of the brackets 26 may play a role.
  • a single clip 26 preferably centrally, is positioned between the sockets 24-1 and 24-4. This clip 26 would then have a slightly greater length L3 to stiffen the side walls 34 and 36 of the first base rail 16-1, that is, bend against one another (see FIG. Fig. 2B ).
  • a major advantage of the system 10 of the invention is that the system 10, and in particular the base rails 16 and the combination of pedestals 24 and mounting rails 18, can be assembled "tool-less".

  • the components 16, 18, 24 and 26 of the system 10 are then simply plugged into each other.
  • a further advantage of the system 10 in the assembled state is the fact that the support rails 18 connected to the sockets 24 are still displaceable in the longitudinal direction X, despite the clips 26 being inserted. Only a fixing of the PV modules 12 to the support rails 18 defines a final relative position of the support rails 18 and the base 24 to each other. This longitudinal displacement additionally simplifies attachment of the PV modules 12.
  • the system 10 is thus characterized by a high ease of assembly and adjustment.
  • the system 10 can also be easily disassembled by releasing the clips 26 from the base rails 16.
  • the system 10 is arbitrarily scalable.
  • the lengths L1 of the base rails 16 can be chosen freely.

  • the system 100 may be installed in a south orientation on the roof 14.
  • the system 100 may be deployed in an east-west orientation on the roof 14, with certain components of the system 100, which will be discussed in more detail below, being duplicated in an east-west orientation such that two of the in Fig. 7 Support rails 102 shown back to back, as will be explained in more detail below.
